Missed pill now discharge

Patient: Hey, ive been on the microgynon 30 for 2 and a half year now and have been sexually active with the same boy since and we’ve both never been with anyone else, i started my 7 day break on 26th september, i started my period and it was the same as usual on 30th, i started my pill again on the 3rd october and finished my period as usual but i missed my pill on the 7th and 8th and took them both with todays, the 9th, and when i went to the toilet i noticed a brown discharge that i would usually get on the last day of my period, is this normal? thanks.

Doctor:
